The Oldsmobile 558711 330 block forged crankshaft (NOS) can be a valuable asset for those seeking a high-quality, durable crankshaft for their Oldsmobile engine. Here are some pros and cons to consider:

1. Forged: Forged crankshafts are stronger and more durable than cast crankshafts. They are less prone to failure under high horsepower and high rpm applications.

2. NOS (New Old Stock): NOS parts are unused, original equipment parts that were manufactured a long time ago but have remained unopened. This can guarantee authenticity and high quality.

3. Suitability: This crankshaft is specifically designed for the Oldsmobile 330 block, ensuring a perfect fit and compatibility with other engine components.

1. Cost: NOS parts can be expensive due to their rarity and high demand.

2. Availability: Due to their age and rarity, these parts may not always be readily available.

3. Compatibility Issues: While designed for the Oldsmobile 330 block, this crankshaft may not be compatible with all aftermarket or modern performance parts.

If you're looking for a durable, high-quality crankshaft for your Oldsmobile 330 block and are willing to invest in a NOS part, the Oldsmobile 558711 330 block forged crankshaft (NOS) could be a great choice. However, be prepared for a higher cost and potential compatibility issues with aftermarket parts. It's always a good idea to research and consult with a knowledgeable mechanic before making a purchase.

If the cost and potential compatibility issues are a concern, consider researching and purchasing a forged crankshaft from a reputable aftermarket manufacturer. While not NOS, these crankshafts can offer similar durability and quality at a potentially lower cost. Always ensure that the aftermarket part is compatible with your engine and any aftermarket performance parts you plan to use.
